摘要： An apparatus, method and system are provided for routing a broadcast data frame in a mesh network with multiple mesh portals. In the mesh network, every mesh point selects and registers its default mesh portal. A mesh portal enters its address in a destination address field of a broadcast data frame received from outside of the mesh network and broadcasts the data frame to inside of the mesh network. The mesh point processes a received broadcast data frame relating to its registered mesh portal, thereby preventing the broadcast data frame from being redundantly transmitted in the mesh network.

摘要： A method and system for establishing multiple channels between nodes each having a single radio interface in a mesh network supporting multiple channels are provided. Each node in the mesh network initially generates a neighbor node table, taking into account at least one traffic channel temporarily established for data transmission to a neighbor node. The neighbor node table is updated when a traffic channel is established for data transmission to the neighbor node, and the neighbor node table is updated according to channel use information of the neighbor node received from the neighbor node or channel use information of a node two hops away.

摘要： Provided is a method for transmitting beacon timing information from a transmission node in a wireless Local Area Network (LAN) mesh network. In the method, each of a plurality of nodes transmits a beacon signal with its unique offset within a beacon signal transmission time period and the transmission node periodically transmits beacon timing information including a first unique offset within the beacon signal transmission time period. The transmission node sets a second offset different from the first offset and transmits probe beacon timing information including the first offset and the second offset.

摘要： A power saving method of the present invention is provide for a wireless sensor network including a plurality of sensor nodes each transiting between a power saving mode and a transmit/receive mode, determines whether or not there is no transmit or receive data, enters the power saving mode if there is no transmit or receive data, and controls power consumption on the basis of signal-to-noise ratios in the power saving mode. In the power saving method of the present invention, it is possible to minimize the power consumption regardless of nodes density and without an adverse effect on the connectivity of the network, since the sojourn times of the sleep and idle states are determined adaptive to the interference level from neighboring nodes.
